VENTILATOR AND DUST-ARRESTER.

SPECIFICATION forming part of Letters Patent No.458,538, dated August25, 1891.

Application filed February 19, 1891. Serial No. 382,090. (No model.)

To all whom, t rltctlz/ concern:

Be it known that I, ADOLPH OLsEN, a citizen of the United States, and aresident of Boston, in the county of Suffolk and State of Massachusetts,have invented new and useful Improvements in Ventilators andDust-Arresters, of which the following, taken in connection with theaccompanying drawings, is a speciiication.

This invention relates to improvements in ventilators anddust-arresters, and is particu larly well adapted for use onpassenger-cars for the purpose of admitting air into the car and toexclude dust and cinders.

Theinvention, although especially designed for use on passenger-cars,may be equally well employed as a ventilator and dust-arrester in otherplaces without departing from the essence of my invention.

The invention is carried out as follows, reference beinghad to theaccompanying drawings, wherein- Figure l represents a plan view showinga portion of the top as removed. Fig.I 2 represents a longitudinalsection on the line X X, shown in Fig. l. Fig. 3 representsabottom planview, partly broken. Fig. 4 represents a cross-section on the line Y Y,shown in Fig. l; and Fig. 5 represents a horizontal section on the lineZ Z, shown in Fig. 2.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

The device consists of a shell or case A, having open ends or mouths AAin its two opposite ends, as shown, through one of which the air isforced,according to the direction in which the car is being propelled.lVithin each of said mouths is arranged a series of inclined deectors ca a, with intervening spaces ct a', such deflectors having their upperedges preferably curvedinward, as shown in Fig. 2. Each mouth Acommunicates with an exit-port B in the bottom of the shell A, throughwhich the dust and cinders are eX- pelled after striking against theinclined deflectors o, c a, as shown by arrows in Fig. 2. Inside of thedetlectors a a ct is in each end of the case A an air-chamber C, whichis in communication with a longitudinal air-re- .shown in Fig. o.

ceiver D, having a perforated bottom d, as shown in the drawings. Thelongitudinal airreceiver D is placed into and out of communication withthe receiving-mouths A through the medium of opening and closing gates Qr wings yI, arranged, respectively, at opposite ends of theair-receiving chamber D in such manner that when the gates or wings areclosed they practically constitute continuations of the partitions E,an'd thereby prevent ber DE, r

F is awater-trough in the lower part of the case A, the water in whichserves partly to arrest such dust and cinders that may pass with the airthrough the perforated bottom cl and to moisten the air before it ispermitted to enter the car. Within the case A is at the side and top oftheair-receiver D a chamber G, having at its top an exit-pipe g, leadingto the car or apartment that is to be ventilated, and within saidchamber G is locateda preferably flattened tube H, made of wire gauze ornetting and containing sponge or absorbent h, as shown. The said tube Hextends from and between the vertical division-walls E E and has itslower portion submerged in the water in the trough F, as shown in Figs.l, 3, and 5. a

fff are transverse ribs in the water-trougl;n F for the purpose ofpreventing the splashing and agitation of the water in said trough ifthe Ventilating device is used on a moving 0bject, such aspassenger-cars or other vehicles.

At the ends of the air-receiver D are hinged in a suitable manner at iz' the gates or wings I I, which are connected together in` such amanner that when one is open the other one is closed. This is donepreferably by means of a light spring rod or wire K, pivoted in its endsto the said gates or wings and guided in a suitable manner through aloop or eve k, fastened to one side of the air-receiver D, as

" The said gates or wings may, however, be connected in any othersuitable manner without departing from the essence of my invention.

L in Fig. 2 represents the floor of a passenger-car or other vehicleinto which the air is to beintroduced after passing through my 6c i thepassage of airinto the air-receiving cham- ICO improved Ventilating anddust-arresting device.

The operation of my inventiofnAis as follows: If the car is moved in thedirc \on of arrow shown' in Fig. 2, the air will forced in through theright-hand mouth A' and in so doing dust, cinders, the., will bedeiiected by the inclines a c and caused to pass downward and outthrough the port B, as shown by arrows in said Fig. 2. The air will beforcedin through the openings a a into the right-hand chamber C and fromthe latter into the chamber D, the force of the wind causing the forwardwing or gate I to be swung open and the opposite one closed, as shown inFig. 5. The air passes out-through the perforated bottom d and throughthe perforated moisture-containing tube H into the chamber G and throughthe exit-pipe g into the car or other vehicle o r room that is to beventilated. From the pipe g may be led distributing-pipes to any desiredpart or parts of the car. A division-plate m in Fig. 4 connects theupper parts of the air-receiver D and tube H, so as to prevent the aircoming out at the perforated bottom d from reaching the exit-pipegwithout first passing through the saturated absorbent in the perforatedtube H, by which the air is moistened and such particles of dust orcinders which may have passed through the perforated vbottom d arearrested.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim- 1. Adust-arresting ventilator consisting of the case A, having at its upperside an airoXit gand at each end an air-receiving mouth A', alongitudinal airreceiving chamber D,

having a perforated bottom d, a pair of connected automatic valves I,governing the flow of air from the air-receiving mouths to theairreceiving chamber, a water trough or chamber below the perforatedbottom of the air-receiving chamber, and a moisture-tube H, arrangedbeside the air-receiving chamber, containing an absorbent material anddipping into the' water trough or chamber for the flow of airtherethrough in transit to the airexit at the top of the lease,substantially as described.

' 2. A dust-arresting ventilator consisting of a case A, having at itsupper side an air-exit g and at each end an air-receiving mouth A',containing a gang of separated dust-deflecting plates ct and provided atthe lower end with a cinder-discharging port B, a longitudinalair-receiving chamber D, interposed between the receiving-mouths andhaving a perforated bottom d, a pair of connected automatic valves I,governing the How of air from the air-receiving mouths to theair-receiving chamber, a water trough or chamber below t-he perforatedbottom of the air-receiving chamber, and a longitudinal moisture-tubearranged beside and coextensive in length with the air-receiving chambercontaining absorbent material and dipping into the Water trough orchamber, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this llth day of February, A.D. 1891.

ADOLPH OLSEN.
